🌟 Details of the construction and benefits of LB30 solid cardboard

• Durability and rigidity: solid cardboard 400 g/m² effectively protects against crushing and deformation, securing the contents even in more difficult transport conditions.

⚖️ Cardboard envelopes vs bubble envelopes - when to choose each of them?

Both types have their advantages, but work best in different situations. Here is a brief comparison:

➡️ When is it worth choosing a solid cardboard envelope?

• Content cannot bend or crush: documents, diplomas, photos or graphics requiring protection.
• You care about ecology: envelopes are 100% paper, without plastic inserts; easy to recycle.
• Professional appearance is important: a cardboard envelope looks solid and aesthetic.
• Product has a regular, flat shape: ideal for books, discs, catalogs, documents.

➡️ When will a bubble envelope be better?

• Content is sensitive to shocks: delicate electronics, glass or ceramic parts.
• You send small, irregular items: bubble wrap adapts to the shape, cushioning the content.
• Lower packaging cost matters: bubble envelopes are often cheaper and easily available.
• Ecology is of less concern: harder to recycle due to the foil layer.

In practice, many companies combine both solutions, depending on the type of goods sent and the required level of protection.
